01

What is PDA (Pentadeca Arginate)?

Plain language first. The technical label stays, but it never stands alone.

Overview

PDA (pentadeca arginate) is a more stable, arginate-salt cousin of BPC-157. In plain terms: it aims to do the same repair job, healing gut, tendon, and muscle, while lasting longer in the body. It is very new.

What it's used for

A newer, more stable cousin of BPC-157, used for the same thing: faster healing of gut, tendons, muscle, and inflammation. It is marketed as longer-lasting.

02

How does PDA (Pentadeca Arginate) work?

What it does in the body, and where.

PDA is BPC-157 as an arginate salt rather than an acetate salt. The peptide chain is the same; the counter-ion is different.

  1. 01
    The repair mechanism is BPC-157's
    Blood vessel growth and repair signalling, with the same animal evidence behind it.
  2. 02
    The arginate form is claimed to be more stable
    Better shelf life and survival in the body. This is a formulation claim from vendors, not something established in published work.
  3. 03
    It is very new and essentially unstudied
    Even by the standards of this category, there is almost nothing published on PDA specifically as distinct from BPC-157.

03

What else is it used for?

Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

04

How much, and do you cycle it?

The range, and whether you take breaks.

0.25 up to 0.5 mg per day (start low, increase slowly), 1-2x daily. Commonly run in 4 to 8 week blocks, like BPC-157Community practice

Same convention as BPC-157, which it is a salt form of. No human study has tested a duration.

How do I dose and price it?

Enter your vial and your dose. Pick a mix. We show the draw and the cost.

The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.

How do you store it?

Before mixing, and after.

Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.

Unmixed lyophilized PDA (Pentadeca Arginate) keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.

07

What are the side effects and cautions?

Known cautions and warnings for this compound.

Who should avoid it

Check these before anything else.
  • No published human trials exist, so no contraindications are established
  • Pregnancy
  • Active cancer, as a precaution given the healing mechanism

Stop and get help

These are emergencies. Seek care.
  • Signs of an allergic reaction
  • Anything unusual, given the absence of human data

Common effects

Expected, and usually mild.
  • Unknown in humans. Despite heavy marketing, there is no published human trial data

Where this page says nothing is established, that means nobody has studied it, not that a compound is safe.

What these words mean

Show glossary +
Titrate
Starting at a low dose and increasing it slowly over time so your body adjusts and side effects stay mild.
Subcutaneous
An injection just under the skin, into the fat layer, usually with a short, thin insulin needle.
Intramuscular (IM)
An injection into a muscle, using a longer needle.
Reconstitution
Mixing a powdered peptide with liquid (bacteriostatic water) so it can be drawn into a syringe.
Bacteriostatic water
Sterile water with a tiny amount of preservative, used to mix powdered peptides.
Concentration
How strong the mixed peptide is, in milligrams per milliliter (mg/mL). More water makes it weaker; less water makes it stronger.
Units (on the syringe)
The marks on an insulin syringe. 100 units equals 1 mL. They measure how much liquid you draw, not the dose in milligrams.
mcg and mg
Units of dose. 1 milligram (mg) equals 1,000 micrograms (mcg).
GLP-1
A natural gut hormone that lowers appetite and blood sugar. Drugs that copy it, like semaglutide, are used for weight loss.
Growth hormone secretagogue
A compound that nudges your body to release more of its own growth hormone, rather than injecting the hormone itself.
Half-life
How long a compound stays active in your body. A longer half-life means you inject less often.
Peptide vs small molecule
A peptide is a short chain of amino acids. A few items here (like MK-677 or methylene blue) are small molecules, not true peptides, but people use them the same way.
Research only
No approved dose or use in people. Sold for research and not reviewed by the FDA for safety or quality.
Investigational
Still being tested in clinical trials and not yet approved or legally sold for general use.
Banned in drug-tested sport
Prohibited by the World Anti-Doping Agency (WADA); using it can disqualify a competing athlete.
